A spawn room issue

Ok, so I have a spawn room issue:
First, when I spawn as a RED player (which is the team the spawn room in question is for), I get the usual issue that one would get when a spawn is stuck in the floor (no weapons, can't move, etc.). However, none of the spawn points are stuck in the floor. Or the roof. Or the surrounding walls. All the brushes were set up according to the development wiki's "Making a spawn room" tutorial.

When I spawn as a BLU player (which has no spawn room yet), I can move around. I think the spawn problem might have something to do with this: in the bottom of my spawn I have a hole to allow players to drop down to the tunnel below. If I look up through the hole as a BLU player, I can see a func_trigger block.
Help?
